Be it known that I, Joux A. (`oL|-:, a ritizen il the l nited States,residing at Chicago,

`in the county nl' Vonk and State of illinois,

mmneetinn n ithst reet water nmins and pipes nrnter underground pipes`it has been found n eeessjarv in order to give ueeess tothe pi )e nrmain to take up the pavement and ig down tu 'the main or pipe. This wascostly aiul ineonvenent, as the opening in the" grolnnl had tu he closedand the pavement rehid when the test had heen eonelnded. In ease vit wasdesired to repeat the test at that point it eenld only he done h v alike operaY ln order to avoid this, I provide the eonstruetion forming,rthe subjeetnnatter of thisl a iplieatiun, whit-h has for its object theproviding of a permanent means at desired A points. whereby thepitotneter een Vhe easily and Init'ltly applied and removed from themainand pipe` of a town, eit v, or other eirrnhiting r system.

lt consists. mainly, in providing'at the req'- uisite puntsnf the pipenr main a small easing provided with an easilvemovable eoi'er, witlnnwhieh is lueated a valved passageor/ pipe emnxntmieating with theinterior of the pipe ur main in respeet tu whieh the test is tol eiliade. Through this pi )e nr passage the pittura-ter can he intrmlneetlo the interior of the pipe or main and renmved therefrom at anv time itis tlesiretl.

ln the neemnpanying drawings l have illustrated one forni in whit-h Ihave eontemplated embodying my invention, and said invention isdist-losetl in the l'ollm'ring,r deseription and t'laitns.

Figure l is a view in elevation of the etmnet-tinn or passage tipe withthe int-losing easing in set-tion. `ig. .2 is a vertieal set'- relnovalof the same.

Fig. 3is a detail view showing the lower entl nl in v pitutneter-'rml slidingvalve, to the stem of which is seeured arranged for insertion. Fig. 4 isa transverse seelinn nl' the enniieetinn nr passage pipe and thepitmneter-rml within it.

ln the tlrawingsQA is u c vlitnlrii'nl easing adapted tu lle plntetl inthe ground at the i it can he upvnet point at which it is deemedadvisable to appl) the pitoineter for the tests` desired. This casing isel' castiron similar to other easings i in the water service. It extendsfrom thoo main to the surfacoof; the ground or pavoment and ispreferably provided at the top with an oll'set to receive a detachablecove-r a, The top is also preferably provided with anoutwardly-extending llange a..

The eonneetioner passage pi throughv which the itometeptubes areinserted, as shown `in t e drawings, consists in thisinlstance of thecommon valvcd or open tap b. To the top of this is secured the uidin-seo- 1p tion e. Above this is the valve and a ,vel this is the pi e e,extending upward and which is provided at. the top with a stu 'box orthe lower half of such box, as at t will he seen from my manner of usingthein-L vention that a complete staging-box sgal-u 1^ ways required; butthe gland might be on the rod of the pitometer, se that but one` glandfor eaeh pttometer :nivht be s This, however, is not my relerredconstrue- 8o tion. When the pipes ofp the pitometer are removed,theupper end of the eonnnunicstn ing pipe or assage is preferablycovered by l the renueva aleeover c', which may be attaehed h v adouhlelmyonetjoint or other 85 simple securing means permitting -theeasy This connection or passage pipe is made with a view ofnccommediating my improved pitometer pipe-rod e dpttonleter-pipes g, as9o more particularly shown and descri in my application, Serial Xo.t),3l4. T he .pipesg are necessarily of smallsize and easily lnJure orlient, and to prevent this while inserting them and the rod f I providethe fuiding-seetion e, the interior of which is at its ventral portionmade ot a little greater size than the rnd. The walls above this-aremade of an easy incline or ta er, so that when engaged they will rentert e rod and will loo guide it through the remainder of the passnfewithout permitting the lower ends of tie tubes or pipesl y g tu come incontat-t with the interior ul the nissage.

The valve d l )ruvido with means h v whieli l and elosetl from thesttrfat'e. In this ease i have Ashown a nl the ground.

the bevel-gear il', meshing with the lievelgear d2, which is providedwith the segnare or other forni nf stem d, hy whit'h the -stein of thevalve van he turned tu open or rinse the valve. The gear d can bemounted in any preferred way, a bracket d, secured to the valve-casing,being,lr employed for this purpose in this instance.

The guiding-section c may, if preferred, be located above the Valve d,or such a section may he em loyed both above and below such valve, as siown in dotted lines in Fig. 1.

The manner of placing the pitometer-rod Awith the pipes g 1n position inthe main or water-pipe is as t?) portion of the stuffing-box is p acedupon the pitometer-rod f and the rod lowered into the upper part of thepi e e until the rod reaches a point just above t e valve d. Thestullingbox is then packed and closed by screwing down the gland. Whenthis has been accom plished, the valve yd is opened, as described,

It will be seen that the pipes g g are mount position de- .ed revolublyin the rod f. In insertimr the rod these pipes are turned so that their.ower angular ends are turned inwardly, so that they have no vreater'lateral ex'tent than the rod itself;V This enables me to .make thepassave 0r pipe communicating with the water mam or pi pe of laminimumsize.
